Abstract
ABSTRACTThe influence of flooding with tap water, and with 10 and 20% sea water on the growth, yield and physiological characteristics in hexaploid triticale (X Triticosecale Wittmack) were analysed. The plants were grown in a glasshouse and flooded at the booting stage for 19 d. Flooding seriously affected the growth, yield and physiological activities of the plants. However, the growth and yield were greater in plants flooded with diluted sea water than in plants flooded with tap water. The amount of newly developed roots, photosynthetic rate and accumulation of mineral nutrients in the leaves was greater in sea water‐flooded plants as compared to tap water‐flooded plants. Oxygen concentrations in the diluted sea water were lower than in the tap water 6 d from the beginning of flooding. Leaf water potentials in the plants flooded with diluted sea water were lower than in the plants flooded with tap water until 7 d from the beginning of flooding when the position reversed. Transpiration was slower and stomatal resistance was greater in flooded plants, and were similar irrespective of water quality.
